Abstract

Approximately 26 500 two-prong events were measured and analyzed by the Notre Dame and Pennsylvania groups, independently. From these analyses, 2421 events of the reaction $π^{-} p \to π^{-} π^{+} n$ were obtained. The predictions of one-particle-exchange models with and without absorptive effects are compared with our data for the production and decay of the $ρ^{0}$ and the $f^{0}$ . We have also observed the recently discovered $g^{0}$ meson. The cross sections for $ρ^{0}$ , $f^{0}$ , and $g^{0}$ production are also given.
